Impact of Patient Portal Messaging Reminders with Self-Scheduling Option on Influenza Vaccination Rates: a Prospective, Randomized Trial.
Trial report in Journal of general internal medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatient portal messages have been used in a variety of ways to facilitate improved communication between provider and patient. These platforms have shown promise in many ways for improving various health outcomes and overall communication between patient and provider.
objectiveAssess the impact of automated portal reminder messages and self-scheduling options on increasing rates of annual influenza vaccination.
designThis is a prospective, randomized, controlled study.
participantsAll patients who receive their primary care through an ambulatory primary care clinic at a large, multidisciplinary, academic health center.
interventionsOne group of patients received a portal message reminder to undergo influenza vaccination. A second group received the same message with instructions to self-schedule the vaccination appointment. A third group received no portal message (control). MAIN MEASURES: Rates of influenza vaccination in each group for previously unvaccinated patients in the 2019-2020 influenza season. KEY
resultsFor the group receiving the message with self-scheduling option (n=5408), the in-study vaccination rate was significantly greater than the group receiving no message (n=5621) (15.7% vs. 13.5%; p=0.002). For the group receiving a message alone (without self-scheduling) (n=5699), the in-study vaccination rate was significantly greater than the group receiving no message (15.1% vs. 13.5%; p=0.01). There was no significant difference in vaccination rate between the two intervention groups receiving messages (15.7% vs. 15.1%; p=0.549).
conclusionsPortal messaging reminders increase annual influenza vaccination rates, but the addition of a self-scheduling option did not further increase rates. KEY WORDS: vaccination patient portal messaging influenza.
